The tensor-to-scalar ratio in a G-inflation model
We calculate the tensor-to-scalar ratio in a G-inflation in this paper.In our model,we can avoid the behavior that the contribution of higher order is too much to screen the lower order Lagrangian,or vice versa.Every order Lagrangian of Galileons contribute to the result.Choosing a proper parameter,...
